MAGNETISM Basic Electrical TheoryIn magnetic materials, the atoms have certain areas called domains. These domains are alignedsuch that their electrons tend to spin in the same direction (Figure 19).Figure 19 Magnetic DomainsThe alignment of these domains results in the formation of magnetic poles at each end of themagnet. These poles are called the north pole and the south pole. The law of magnetism statesthat like magnetic poles repel and unlike magnetic poles attract one another (Figure 20).Figure 20 The Law of Magnetic Attractionand RepulsionES-01 Page 28 Rev. 0
